SHOE-CHANNELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 577,814, dated February 23, 1897. Application filed August 29,1895. Renewed September 19, 1896. Serial No. 606,447. (No model.)

To all whom it may concern:

Be it known that we, ERNEST M. WHITE, of Philadelphia, Pennsylvania, and J AOOB M. SPROW, Jr., of Camden, New Jersey, citizens of the United States, have invented certain Improvements in Shoe-Channeling Machines, of which the following is a specification.

Our invention relates to certain improvements in machines for channeling the soles of boots and shoes; and the main object of our invention is to so construct the machine that the sole will be clamped in a stationary position and the channeling-tool will be traversed around the sole, as fully described hereinafter.

A further object of the invention is to combine the machine with a sole rounding or cutting machine so that the sole can be cut to shape and channeled and grooved in one operation.

These objects We attain in the following manner, reference being had to the accompanying drawings, in which- Figure l is a view of sufficient of a machine to illustrate our invention. Fig. 2 is a plan view showing the channeler combined with a sole rounding or cutting machine. Fig. 3 is an enlarged View showing the channeler in action. Fig. 4 is a perspective view of the head with the cutting-k nives. Fig. 5 is a plan view illustrating a machine to be used only as a channeler and groover. Fig. 6 is a view illustrating a machine in which the channeling and grooving knives are mounted at one end of the turret and the sole-rounding knife mounted on the opposite end.A Fig. 7 is a side view of Fig. 6.

W'hile the sole rounding or cutting machine illustrated is of the ordinary construction, the present machine is made in accordance with the patent granted on the 16th day of October, 1894, and numbered 527,676. In this This cam-plate, as well as the rying the cam A', and this table is carried by a bevel-Wheel B2, driven by a pinion B3 on the driving-shaft B4, as clearly shown in Fig. 1, so that the table B will rotate around the standard A3.

Carried by the plate, as shown in Figs. l and 2, are two carriages D and E. The carriage E carries the sole-rounding mechanism, of the ordinary construction, and has a cutting-knife c clamped to the slide F', and this cuttingknife is arranged to cut the soleleather outlined by the former A as the slide bears against the former. The carrier E has rollers e and e2, adapted to the cam-groove o. on the under side of the cam-plate A. The carrier E is connected to the rotating table B by a rod E2. This connecting-rod is attached to a pin directly under the antifriction-roller e', and by this means the carrier E will travel around the former and cut the blank and Will slide upon the table to a limited extent, as indicated bythe cam-plate, so that the cutter will conform readily to the shape of the former A.

The carrier D, having the channeling and grooving knives,is connected to the carrier E, in the present instance by a pin, preferably in line with a roller e2, and the carrier D has a roller d, adapted to a groove in the camplate, so that the carrier D will conform to the outline of the former A, at the same time being conveyed aroundthe former bythe table B through the carrier E. Thus by providing suitable knives for channeling and grooving the sole, as shown in Fig. 3, the sole can be channeled and grooved while clamped in the sole-rounding machine, thus dispensing with independent channelers. Furthermore, the channel will be properly made 0W- ing to the fact that the same dies or formers which guide the cutters of the sole-rounding mechanism guide the channeler as Well, thus insuring accuracy. As the heel portion of the sole is not channeled, we provide mechanism for moving the channeler away from the sole as it passes around the heel.

Mounted directly below the heel portion of the former A is a cam F. This cam is adjustably secured to the iixed portion of the machine, so that it can be regulated to accommodate different-sized formers.

Resting' against the cam F is a roller d', carried by a slide d2, connected to the slide cl3 of the carriage D. As the channeling-knife is mounted on this carriage, the knife will be moved away from the heel portion of the sole as soon as the roller comes in Contact with the cam F. As soon as the carriage passes around the heel the channeling-tool will be again thrown into action by the springs within the carriage D. The slide d3 rests against the former A, and to this slide is pivoted at d4 the head di". Carried by the head d5 is a cross-slide d, adjusted laterally by a feedscrew 6X7, and on this slide is a tool-carrier d8,

. longitudinally adjustable and carrying the channeling-knife i', grooving-knife i', and presser-foot 2. The presser-foot rests upon the upper surface of the sole and is held down by the spring 3, mounted between the head d5 and a nut on a stem i4, projecting from the slide d3. A set-screw i5 is used to regulate the head in respect to the slide cl3. Thus it will be seen that the head, with the tools, is free to move on the pivot d4, as the head does not rest against the former A, the slide d3, carrying the head, taking all the pressure, and the tools can be adjusted in any position in respect to the former.4

Carried by the slide cl2 is a bolt m, having a pin m', which, when the tool is passing around the heel, engages with the slide cl3 and prevents it turning laterally on its pivot di). A spring m2 forces the pin into engagement with t-he slide. When the carriage D is passing around the sole, the bolt m is pushed back by the former A, releasing the slide d3, which moves on the pivot d" to accommodate itself to the former and sole.

In Fig. 5 we have shown a latch m3, acted upon by the bolt, the latch in this instance engaging with the pivoted head, and in this iigure we have shown a channeling-machine without the rounder. In this case the ,soleblank, which has been previously cnt out on a rounding machine, is clamped on the former, and pins a2 on the former hold the sole in proper position. The pins, however, do not project to such an extent as to interfere with the channeler.

In Figs. 6 and 7 we have shown a turret mounted on the slide, so that the machine can be used as a combined rounding-machine and channeler. In this instance, the roundingknife is mounted at one end of the turret and the channeler and groover on the opposite end, so that the leather blank is clamped in position. The turret is turned so that the rounding-knives will cut the blank to shape, after which the turret is turned so as to place the channeling and grooving knives in position, after which the machine is again set in motion, and as the carriage passes around the sole the channeling and grooving knives will be thrown into action and channel the sole.

Various modifications of the channeling and grooving knives may be used, and slides of different designs may also. be used without departing from our invention.

Ve claim as our inventionl. The combination of a former, a clamp for the sole, a cam-plate, a carriage engaging with said cam-plate, a slide on the carriage movable toward and from the former, a channeling-knife on said carriage and a cam so situated under the heel portion of the former that as the carriage passes around the heel the slide will be moved laterally away from the sole, substantially as described.
